nothing but trouble rebuild! (fw)

been wanting to make a nice cnc'd feather weight flipper to go with TS3 kinda thing for a while so started it just over a week ago.- making it sorta flow! style as i've always liked the look of it.

picture of the base plate below, 10mm with 6mm deep pockets, the 2 cental slots are for the bulkheads to fit into when they are made.

when both motor gear boxes are done and bolted on will weigh an estimated 2.8kg. Thats without weight saving on the motor mounts yet too.

im going to have the ram bolt to a billet thats then to the base, this will allow me to swap rams out easily, as im putting a low pressure ram in for now but would like to make my own eventually perhaps on full pressure once i no how to use works lathe!

I do like a cnc' ing its always so neat, an exciting project

[daveimi]

This looks good! What will the final shape be like?

[calumco]

Cheers, and sorta kronic style or like the feather weight flow

[calumco]

almost finished off! drive wise anyway

base plates done near enough with 5.2mm holes and counter bores on the underside for the m5 capheads holding everything to the base.

motor mounts are done with weight saving, and drilled and tapped into the axle holes for an m6 grub screw to eventually go in and hold the axles and stop them spinning.

overall i can take loads more weight out yet but i wana wait untill the robots a bit more together just so i don't end up taking out material where it might be needed still

few more pics, plan is to have a victor per motor and will mount it to the face thats inline with the motors edge on a little plate or something

[calumco]

more bits done, got round to designing the bulkheads- only got one made thou as it was originally free 12mm thick plate so had to be skimmed down 10mm which took longer than i thought to sort out.

made a plate for the base of the ram, which will connect the the base plate and will also connect to the sides of the bulkheads with 3 m6 bolts each side.

loads more bits to make yet thou, link holder, speed controller holder, battery holder and loads of side holes for armour and various grub screws etc. wana mount internals above and beside the drive motors.

goin with low pressure for now, as the old one ran at about 8 bar and was decent for LP, this chassis will take better forces so will 10 bar it for now untill i make a FP ram one day- but im not in a rush for that.

Really really pretty machining. This will be one of the big wigs when it's finished.

That drive train looks really nice; and powerful too!

[calumco]

cheers guys

more done, took the rads off the bottom of the first bulkhead and got it mounted to the baseplate after work....

why you mounted your ram to a plate then that plate to a base plate thats just as thick? looks well heavy...

[calumco]

so that i can put a different ram in eventually and instead of having different holes everywhere i can just make a new plate. Plus with it bolting into the sides of the bulkheads gives it more strength

Designed and machined a lipo box that mounts to the motor/wheel mount.

TS3s lipo holder is ok but not having any foam/padding in has started marking the battery with all the knocks and bumps of the champs. So on this one i allowed for 3mm extra on each side to fit some foam in.

and i no the valves not going to have a great flow rate but im just getting it all working for now and ill see about making it more powerful later on. For what i want it for and for the events it'll do the old robot had a decent flip with the same set up so it'll do me for now.

lots of pics below....

seems ya dont have to place them in the post anymore but anyway more below in the attached thumbnails thing!

This is really cool, do you draw it in the computer and then push it up to a CNC machine to mill the parts?
